SPECIFICATION forming part of Letters Patent No. 629,846, dated August 1, 1899.

Application filed March 24, 1899.v

To all whom it may concern:

Be it known that I, FREDERICK A. W. DAVIS, a citizen Vof the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Separators for Waterworks, of which the following is a specification. l

The object of my present invention is to provide an apparatus by which foreign matter in water may be separated and the water thus substantially clarified, thus puttingit in better condition for subsequent treatment, such as filtration or other purifying process.

An apparatus embodying said ,invention will be first duly described and the novel features thereof then pointed out in the claims.

Referring to the accompanying drawings, which are made a part` hereof and on which similar reference characters indicate similar parts, Figure l is a top orplan view of a fragment of a water-main and apparatus connected thereto embodying my present invention; Fig. 2, a vertical sectional view as seen from the dotted line 2 2 in Fig. l, the connecting'- pipes being shown in elevation; Fig. 3,Y a horizontal sectional view as seen when looking downwardly from the dotted line 3 3 in Fig. 2, and Fig. 4 a transverse sectional view of the` upper portion of a traveling crane suitable to besused in manipulating the apparatus in shifting and cleansing the same.

In said drawings the portions marked A A1 represent two fragments of a water main or con duit. In this arrangement the main is separated into two divisions, as shown, and the ends of the respective divisions lie alongside of each other at a suitable distance apart, and l the opposite ends of the two divisions arel 'capped cir-otherwise closed. As is indicated 1 in Fig. 2a proper and usual arrangement includes a filter interposed between the separators and the division A of the main'or coudnit. The illustration of the filter is merely diagrammatic for the reason that fil-ters for such purposes are of varying forms and sizes, `a common ferm being a sand-bed of consider- 'able area, onto which the water is discharged, so that no special illustration of form or construction is necessary.

I may here remark that the whole apparatus is intended to be located in most cases between sans N0. 710,299. (No man.)

lthe Water-supply and the pumps and that the division A of the main or conduit is intended to represent (in cases of this preferred or usual arrangement) the conduit leading directly into the pumping-station and supplying the f pumps,where, as is commonly the case, pumps are employed. As is obvious, however, the lapparatus may be used also Where the source of the water-supply is at such an elevation that no pumps are required. Between said divisionsA A' of the water-main I place several separators, the construction of which is shown in Fig. 2. These separators are each composed of a preferablyV cylindrical outer casing l, having an internal circumferential flange or rib 2, upon which is placed a bucket 3, having its ends formed of perforated or reticulated material and whichis filled with some suitable substance 4,-, adapted to separate or strain out the impurities from the water. The upper end is held in by a spiderlike structure 5, to which is connected an eyebolt 6, which serves both as a strut, by which the bucket containing the separating material ,is held in place, (being adj usted to bear against the cap or head 7 of the separaten) and also as a lifting-rod, by which said bucket may be removed when desired, as will be presently described.

In operation the Water flows from the division A of the water-main through the pipe a to the lower portion of the separator, passes thence up through the separating material to the upper end of the separator, and thence through the pipe a to the division A of the main, whence it passes onto wherever it is desired to convey it. As has already been indicated, the bucket containing the separating material is held firmly down onto its seat on the flange 2 against any pressure that may be exerted by the water coming from the division A by means of the eyebolt 6, against which the cap or head 7' is strongly forced. In those sections of the apparatus which are in operation the valves e and fu are open and the valve Idin the discharge-pipePis closed. When, however, it isdesired to stop the iiow through any given separating-chamber, the valves t' c' connected therewith are closed, and the water and sedimentin the lower part of the separator may be drawn 'ott through the pipe P byopening the valve e2. The fil- I iOO tering material in the bucket 3 in the course of its use becomes clogged and filled up more or less frequently, according to the condition of the water, by the sediment which is carried thereby, and in order that the apparatus may be rendered most highly effective it is necessary that these buckets should be cleaned as frequently as conditions require. As is best shown in Fig. 1, I employa considerable number of these separating-chambers in order that the iiow of water may be continuous, although some of them maybe shut oft for purposes of cleansing or repair. I have shown three of these separating-chambers, but obviously any number desired may be employed. Situated suitably in relation `to these separators is a trestle, upon which is mounted a traveling crane, which may be of any ordinary or desired construction. This is adapted to be positioned above any one of the separators and to be used in hoisting and transporting any of the several buckets containing the separating or straining material. In using this apparatus the separator to be cleaned having been shut off from the mains by the proper manipulation of the valves, as above described, the cap or head 7 is removed and the elevating mechanism of the crane attached to the bucket therein,which is thereby hoisted out ofthe separating-chamber, and thence moved longitudinally or laterally to such convenient position as is'desired, when, by means of an ordinary hose or other like appliance, Water is applied to the top of the bucket and, running down through the separating material in the reverse direction from that in which the Water passes when the apparatus is in use, Washes out and discharges the sediment which has become lodged therein, thus restoring the same to suitable condi- 4o tion for further use. vIt is then transported back to position and lowered into the separating-chamberand the head to said chamber replaced. Then by a proper shifting of the valves the apparatus is restored to active use.

Having thus fully described my said invention,what I claim as new, and desire to secure by Letters Patent, is- Y In a Waterworks system, the combination, of a water-main in two separate sections, and 5o a separator interposed between and connecting said sections, consisting of a series of cylinders, each connected at oneV end with one section and at the other end with the other section by short pipes containing valves, and a removable bucket containing filtering substance mounted between said ends, the heads of said cylinders being removable to permit of the removal and replacement of said buckets, and means for effecting said removal and 6o replacement, whereby the Iiow of Water through one or more separators may be cut off and said separator cleaned without interrupting the operation of the system, substantially as set forth.

In Witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 20th day of March, A. D. 1899.
